ABSTRACT
Introducción: el papiloma invertido nasal es un tumor nasosinusal primario de comportamiento intermedio, con potencial de malignización y capacidad de recidiva en asociación con mucocele. El manejo quirúrgico de ambas patologías se ha descrito de manera independiente. Caso clínico: paciente con diagnóstico de papiloma invertido nasal Krause III y mucopiocele frontoetmoidal orbitario derecho con destrucción de techo de órbita y pared posterior del seno frontal en quien se realizó el manejo multidisciplinario mediante abordaje endoscópico y abierto sin recidiva luego de un año de seguimiento. Discusión: a la luz de la evidencia actual, el tratamiento del papiloma nasal invertido es quirúrgico recomendando abordajes endoscópicos en estadios I, II y III, y técnicas combinadas en estadio IV. En nuestro caso se realizó una resección endoscópica completa del tumor con frontoetmoidoesfenoidotomía + maxilectomía medial y fresado de inserciones óseas. Para el mucocele frontal, el abordaje debe permitir la remoción de la mucosa sinusal y la secuestrectomía ósea. Teniendo en cuenta la localización lateral y el compromiso osteolítico del techo de la órbita y la pared posterior del seno frontal, se optó por un abordaje abierto mediante un colgajo osteoplástico con cranealización de seno frontal. El manejo de las secuelas orbitarias consistió en la reconstrucción del techo de la órbita y dacriocistorrinostomía endoscópica.
Introduction: Nasal inverted papilloma is a primary nasosinusal tumor of intermediate behavior, with potential for malignancy and relapse capacity in association with mucocele. The surgical management of both pathologies has been described independently. Case report: Patient with a diagnosis of Krause III nasal inverted papilloma and right frontoethmoidal orbitary mucopiocele with destruction of the orbital roof and posterior wall of the frontal sinus is performed using a multidisciplinary approach with an endoscopic and open approach without relapse after one year of follow-up. Discussion: The treatment of inverted nasal papilloma is surgical recommending endoscopic approaches in stages I, II and III, and combined techniques in stage IV. In our case, a complete endoscopic resection of the tumor was performed with frontoethmoidosphenoidotomy + medial maxillectomy and milling of osseous insertions. For the frontal mucocele, the approach should allow the removal of the sinus mucous membrane and the bone sequestractomy. Considering the lateral location, the osteolytic involvement of the orbital roof and the posterior frontal sinus wall, we opted for an open approach using an osteoplastic flap with frontal sinus cranialisation. The management of the orbital sequelae consisted of reconstruction of the orbital roof and endoscopic dacryocystorhinostomy.

Objective To discuss the operative techniques of endoscopic endonasal transsphenoidal surgery for the resection of pituitary adenoma in elderly patients.Methods From June 2003 to June 2012,a retrospective analysis of 42 elderly patients with pituitary adenoma was conducted.Computed tomography (CT) scan,magnetic resonance imaging (MRI) scan,and endocrinological examinations were performed in all patients before operation.All patients underwent endoscopic endonasal transsphenoidal surgery for the resection of pituitary adenoma.Results The tumors were totally removed in 25 cases (59.5％),sub-totally removed in 8 cases (19.1％) and partly removed in 9 cases (21.4％).1 patient died after operaion.Patients were followed up for 6-36 months.The visual acuity and visual field were improved.Hormone replacement therapy were needed in 20 patients due to hypopituitarism.Tumor residuals were found in 12 patients,among whom 5 patients were treated by γ-knife radiosurgery.Conclusions The endoscopic endonasal transsphenoidal operation is minimally invasive and safe for the treatment of pituitary adenoma in elderly patients.The strengthening of perioperative management is the key to the successful operation.
